14/12G-G Chemical Centrifugal Pump , vice impeller seal / packing seal pump
Installation of mechanical seal for slurry pump
1. check the mechanical seal installed type, specifications are
correct.
2. check the size of the slurry pump and the installation of
mechanical seals related to the size of parts, geometric accuracy
and correlation are consistent with technical requirements. The
main aspects are as follows:
(1) the radial runout tolerance of the shaft (or shaft sleeve) that
installs the mechanical seal part, the surface finish and outer
diameter tolerance of the shaft (or axle sleeve).
(2) the verticality of the center line of the axle (or axle sleeve)
is allowed by the combination of the sealing cavity and gland.
(3) install the end of the shaft (or axle sleeve) of the ring seal
ring, install the chamfering and finish of the end of the shell of
the mechanical seal.
(4) the axial displacement of the shaft of the mechanical seal.
3. the installation of mechanical seal process should be kept
clean, and do not allow tools to tap sealing elements, in case of
damage and damage.
4. when installing, the movable and static ring surface should be
coated with a layer of clean oil and turbine oil. The auxiliary
sealing ring (including the movable ring seal ring and the static
ring seal ring) also needs to be coated with a clean oil or turbine
oil before installation so as to ensure the smooth installation.
5. the static ring sealing ring in static ring back after the
sealed end cover, should pay attention not to hurt the static ring
end face, to ensure that the end surface of the static ring and the
end cover is vertical to the central line, and pay attention to the
anti rotary slot alignment anti rotation pin static ring back, but
not in contact.
6. The rotating part of the mechanical seal is fixed to the axle by
two fixed screws on the spring seat. When the screws are tightened,
the working length of the spring must be ensured.
Application of mechanical seal for slurry pump
When stopping, we should stop the slurry pump and stop cooling and lubricating system.
